While we had comedian Kevin Hart in the hot seat to chat about his upcoming film, “Let Me Explain,” we had to ask him about bringing some extra star power to his social feeds with recent (NSFW) Instagram video featuring Evander Holyfield and Mike Tyson.

Hart reveals that on a shoot for the upcoming film, “Grudge Match,” starring Robert De Niro and Sylvester Stallone, he was filming a special scene with Holyfield and Tyson. “Because they were both there, I had a funny idea to do an Instagram video because I love social media and they love it, too, and they helped me.”

He also notes that it was a lot of fun working with them, and a surprisingly relaxed environment. “You would think that what happened in the past kind of bled into their later years, but they both seemed way past it, mature, and they had a mutual respect for one another as professionals.”

Regarding his social media strategy, Hart keeps it simple: “Being real, communicating, being yourself, not letting somebody operate your pages and your feed for you. Just kind of staying true to what you know and what you believe.”
